I am really excited to find this site. I'm Lucas' dad(4) Greg Malcom. Just started my reno-mod of his Dune Racer that was entirely too slow(paw-paw purchase Christmas '16) He never really rode it until I decided to ramp up the power. Initially took 2 12v's off an old Chinese 4 wheeler and put them in sequence 36 volts and it hauled buttocks.....then.....(insert Price is Right loser sound) Its a total rebuild. I was youtube only last week. I hope this site helps. I was born in '73 sponsored skateboarder, no helmet, sketchy ramp at full speed jumper on anything self propelled or with motor. I'm raising my kid offline. Put down the phones! Go fast, jump high, have fun, scare mom!!!
